IMPROVEMENT IN GAS-BURNERS.

Speciicaiion forming part of Letters Patent No. 161,091, dated March 23, 1875 application iled August 11, 1874.

'To all whom it may concern.

Be it known that I, CHARLES E. BALL, of the city and county of Philadelphia, and State of Pennsylvania, have invented a certain new and useful Improvement in Argand Gas- Burners; and I do hereby declare the following to be a full, clear, and exact description thereof, reference being had to the accompanyin g drawings and letters of reference marked thereon.

The nature of my invention consists of a burner, the annular portion of which is form ed of a single plate of duotile met-al, and united to the spider or branched tubular portion ot' the burner by riveting or expanding the ends ofthe branches in apertures formed in the ring, and afterward closing theseam of the ring by compressing the edges together, and afterward perforatin g jet-apertures in the usual manner.

Figure l shows a plan of the completed burner; Fig. 2, a sectional'elevation of the same inthe plane indicated by the dotted line in Fig. 1. Fig. 3 shows, in vertical section, the burner before the seam in the annular portion is closed; and Fig. 4i shows the branched .tube before it is inserted in the ring.

The same letters of reference apply to the same parts in the several ligures.

A represents the annular portion of the burner; B, the screwed tube for attaching it to the gas-fixtures, and O the branches for conveying the gas from the tubeB to the annular tube A. The ring A of the burner is formed by spinning` in the form shown in Fig. and being perforated for the insertion of the branches O. The branches O are shouldered down, as shown at O in Fig. 4, the metal oi' the ring A surrounding the several branches C of the tube B being firmly clamped between the shoulders O and the expanded ends of the tubes O, so that any changes of temperature in the ring A do not loosen the joints formed between the tubes C and' the ring A.

While expanding tubes of itself is an old and well-known thing or process, it has never been applied to argand gas-burners 'of any class, because the branches .C of the central tube B were longer on opposite sides of the tube than the diameter of the ring, and the ring would not admit of the tubes being inserted therein.

To accomplish this, I bend the various branches downward a sufficient distance to allow them to be inserted in the holes in the ring, and then press the tube B downward, which forces the ends of the branches O into the ring A, after which they' are expanded 5 andthe ring A being left open on the outside, an expanding device may be placed in the ends of the branches O on the inside of the ring and the branches expanded, when the ring is closed, as described.

Aften the branches O are inserted in the ringAthe ends of the branches are expanded by forcing a tapering steel punch into them, the seam in the ring A being left open for the purpose of introducing the punch.

After the branches are fastened in the manner stated, the upper edge A1 is pressed down into close contact with the edge A2, as shown in Fig. 2, and the periorations D for the delivery of the gas are drilled.

The advantages of the burner so made are, that the soldering process can be dispensed with, and the burner, being not liable to obstructions from solder in the tubes, can be made smaller, thus economizing material, and rendering the burner practicably saving in costo production by diminishing the labor required to make it.

I claim- In an argand gas-burner, the ring A, constructed as described, to open on the outside, in combination with the tube B, having branches O, provided with shoulders O', expanded into the ring A, all substantially as and for the purpose herein set forth.
